I have lots of close up shots of individual components now, so I can provide some detailed intell for anyone who needs it.

I have a couple of questions myself though, about parts that may have been modified.

1. Is there a service manual/workshop manual for the Mark 2 Midget engine? (I have the ops manual and parts list thanks to Jack's postings)
2. Is there a service manual/workshop manual for the mower as a whole?
3. In the absence of those, does anyone have accurate information about the sprocket configuration (under the left hand external cover). I'm not sure the idler sprocket I have is original. If anyone has the actual tooth count of the sprockets it would be helpful.
4. Does anyone know if the main clutch (the assembly with the cork clutch plate and the belt pulley) "pulls" off the crankshaft?
